4 printings, newest first. Prices are the market figures Scryfall publishes, refreshed nightly — a printing with no figure shows a dash rather than a zero, because Scryfall genuinely publishes none for some of them.

Prices from Scryfall, which tracks the TCGplayer and Cardmarket markets. They move daily and are a guide rather than a quote. Search TCGplayer for Fiendish Duo — a name search across every version, for the printings TCGplayer publishes no direct link to.

Aggregated from Commander games tracked in TurnZero HQ. Every figure counts decks and games only — no individual deck list, player or playgroup is identified. Win rates are withheld below 5 completed games, where the sample is too small to mean anything.
